We present a new method for imposing and testing concavity of a cost function using asymptotic least squares, which can easily be implemented even for cost functions which are nonlinear in parameters. We provide an illustration on the basis of a (generalized) Box-Cox cost function with six...

This study is the first to estimate mothers’ marginal willingness to pay (MWP) for job amenities directly. Its identification strategy relies on German maternity leave length. The key aspect of the maternal leave framework is that mothers can decide whether and when to return to their...

This paper presents new evidence on the causal relationship between fertility and female labor supply. We particularly focus on how informal employment affects post-fertility labor supply behavior of mothers. We employ an instrumental variable strategy based on an unused data source for twin...

The pattern of joining the labor force only at an advanced stage of the life-cycle was widespread among American women in the 1960s and 1970s, but not since the 1980s. To explain this change we conduct a theoretical analysis of the interrelation between women's lifetime labor supply choices and...
